A Pilot Study of Telehealth Mindfulness-Based Cognitive Therapy for Depression in Parkinson's Disease.

Introduction: Parkinson's disease (PD) is characterized by high-rates of depression with limited evidence-based treatment options to improve mood. Objective: To expand therapeutic options, we evaluated the feasibility and effect of a telehealth mindfulness-based cognitive therapy intervention adapted for PD (MBCT-PD) in a sample of participants with DSM-5 depressive disorders. Methods: Fifteen participants with PD and clinically-significant depression completed 9 sessions of MBCT-PD. Depression, anxiety, and quality of life were evaluated at baseline, endpoint, and 1-month follow-up. Results: Telehealth MBCT-PD was feasible and beneficial. Completion rates exceeded 85% and treatment satisfaction rates were high. Notable improvements were observed for depression, anxiety, and quality of life over the course of the trial. Conclusion: Telehealth MBCT-PD shows promise and warrants further evaluation via randomized clinical trial with more diverse participants. Such research holds the potential to expand the range of therapeutic options for depression in PD, thereby setting the stage for personalized care.

Attentional control may be modifiable with Mindfulness-Based Cognitive Therapy to Prevent Suicide.

OBJECTIVE: To test whether Mindfulness-Based Cognitive Therapy to Prevent Suicide (MBCT-S) is associated with improvement in attentional control, an objective marker of suicide attempt. METHOD: In the context of a randomized clinical trial targeting suicide risk in Veterans, computerized Stroop and emotion Stroop (E-Stroop) tasks were administered 3 times over 6-months follow-up to 135 high suicide risk Veterans. Seventy were randomized to receive MBCT-S in addition to enhanced treatment as usual (eTAU), and 65 were randomized to eTAU only. E-Stroop word types included positively- and negatively-valenced emotion, suicide, and combat-related words. Interference scores and mixed effects linear regression analyses were used. RESULTS: Veterans receiving MBCT-S showed a more favorable trajectory of attentional control over time, as indicated by performance on two E-Stroop tasks. Combat-stress interference scores improved over time among Veterans in MBCT-S. Interference processing time for negative affective words deteriorated over time among Veterans receiving eTAU only. CONCLUSIONS: MBCT-S may effectively target attentional control, and in particular reduce processing time during affective interference, in high suicide risk Veterans. Future studies to replicate these findings are warranted.

Mindfulness-Based Cognitive Therapy for Preventing Suicide in Military Veterans: A Randomized Clinical Trial.

Objective: This study evaluated whether Mindfulness-Based Cognitive Therapy for Preventing Suicide Behavior (MBCT-S) effectively augmented treatment-as-usual enhanced for suicide prevention (eTAU).Methods: From December 2013 through March 2018, veterans (N = 140) at high risk for suicide were recruited mostly (88.6%) during a suicide-related inpatient admission and randomly assigned to either (1) eTAU augmented with MBCT-S or (2) eTAU only. MBCT-S began during inpatient treatment (2 individual sessions emphasizing safety planning) and continued post-discharge (8 group sessions emphasizing mindfulness skills and elaborated safety planning). Four follow-up evaluations occurred over 12 months, and primary outcomes were (1) time to suicide event and (2) number of suicide events. Secondary outcomes were time to and number of suicide attempts, proportion with acute psychiatric hospitalization, and change in suicide-related factors (eg, depression, hopelessness, suicidal ideation).Results: Relative to eTAU, MBCT-S did not significantly delay time to suicide event (hazard ratio = 0.86; 95% CI, 0.52-1.41; P = .54), but did reduce total number of suicide events (MBCT-S: 56 events; eTAU: 92 events; incident rate ratio = 0.59; 95% CI, 0.36-0.99; P < .05). There were no significant differences in time to or number of suicide attempts. In a post hoc analysis, however, MBCT-S significantly reduced the proportion of participants attempting suicide (P < .05). MBCT-S also reduced the proportion with a psychiatric hospitalization. No significant between-group differences emerged on any suicide-related factors.Conclusions: Adding MBCT-S to system-wide suicide prevention efforts produced mixed findings on the primary outcome (suicide events) and promising findings on other important outcomes (suicide attempts, psychiatric hospitalizations). MBCT-S should continue to be examined in future research.Trial Registration: ClinicalTrials.gov identifier: NCT01872338.

Innovating Parkinson's Care: A Randomized Controlled Trial of Telemedicine Depression Treatment.

BACKGROUND: For several decades, a myriad of factors have contributed to the inadequate diagnosis and management of depression in Parkinson's disease (PD), leaving up to 60% of significantly symptomatic patients untreated. Poor access to evidence-based neuropsychiatric care is one major barrier to achieving optimal Parkinson's outcomes. OBJECTIVE: The goal of this study was to compare the efficacy of individual Parkinson's-informed, video-to-home cognitive-behavioral therapy (experimental group), to clinic-based treatment as usual (control group), for depression in PD. METHOD: Ninety United States military veterans with clinical diagnoses of both depression and PD were computer-randomized (1:1) to either the experimental or control group; randomization was stratified by baseline antidepressant use and blind to all other baseline data. The acute treatment period spanned 10 weeks and was followed by a 6-month extension phase. The Hamilton Depression Rating Scale was the a priori primary outcome. Depression treatment response was defined as a score ≤2 on the Clinical Global Impression Improvement Scale. All statistical analyses were intent to treat. RESULTS: Video-to-home cognitive-behavioral therapy outperformed clinic-based treatment as usual across three separate depression measures (P < 0.001). Effects were observed at the end of acute treatment and maintained through 6-month follow-up. Number needed to treat (based on treatment response classification) was 2.5 with an absolute risk reduction of 40%. CONCLUSION: Video-to-home cognitive-behavioral therapy may be an effective intervention to bypass access barriers to specialized, evidence-based depression care in PD and to address the unmet neuropsychiatric treatment needs of the Parkinson's community. © 2021 International Parkinson and Movement Disorder Society.
